ALMAGEST, compounded of the Arabic al and μειστη, an epithet of distinction conferred on a collection or book
composed by Claudius Ptolemy, containing various problems of the ancients both in geometry and astronomy. Other collections have received the same name. Thus, Riccioli has published a book of astronomy, which he calls the New Almagest; and Plukenet, a book which he calls Almagestum Botanicum.
